CAR-TIPPLE.

Application tiled September 28. 1917.

arrangement and combination oi' apparatus and mechanism associated with a rotarytip ple for properly handling the cars through the tipple in the overturning and dumping operation of the latter. The improved apparatus and devices here illustrated are designed more particularly for use in combination with a tipple'of the kind known as a rotary ti )ple7 1n which the cars, singly or in trips oi twoor more, enter a rotating structure and are overturned sidewse to discharge their contents. The cars are ordinarily brought to the tipple in trains along y a connecting stretch of xed track which joins a pair of rails in the lower part of the tipple, and after the dumping operation is completed the cars leave along a correspond ing length of stationary track which meets vthe tipple at its opposite endl; it having heretofore been found to he practical to provide the cars with swiveling couplings so that the dumping operation may -be carried on without uncouplmg the cars in the train. The present invention relates more particularly to means for handling a train of loaded cars in the approach to the tip le, moving them forward intermittently a istance corresponda to the length of one or more cars. periodica y and automaticall stopping the train in auch manner as to s ot one or more cars -in the tipple and olding the train stationary for each dumping operation, and then continuing its movement te Pass the unloaded cars out of the tipple and kpain/ing drawings in which ntroduce one or more loaded cars for the 15` nextV operation.

As shown in .said drawings, l() indicates` in outline merely a cylindrical tipplc structurc which :nay he of an)Y well known type. the same living mounted on wheels. 11, and arranged to rotate about a horizontal axis. The cylinder is open at each cud and is provided with rails extending through its entire length to receive 4one or more cars, which latter enterA the tipple along a stretch of stationary truck, 15, pass through the tip ile, and leave over a length of track 20. 'lhe cylinder .1 0 may be i'nadc of any, practical length according to the number of carsA which it is intended to accommodateand in thc dumping operation the cars may be hroughtixp `in a long train and overturned auccessivel)` without; being uncoupled. A rotary tipple or structure vsimilar' to that here sliown. with stretches of fixed track plan view of the saine parts particular design parts are no` part used heretofore, and the. and construction of these of the present invention.

Ad'acent to the section of track 15 approac ing the receiving end of the tipplc 10 is arranged the driving mechanism for advancin the cars into and through the tipple throng x-a long chain, 25, which latter is arranged hetween the two rails. Accordin ly there are journaled bencaththe track bed a pair oflargc sprockets, 26 and 27, over which is trained the chain 25; and on this chain there are fixed at the required dis-l tonces car pushers for engaging the cars. One of these car pushers is illustrated in Figs. 6 and 7 and includes two airsof flat plates, 30`and 81, which take t e lplace of ythe two side plates of an ordinary link but los .J Each of the lovers. 35, 35. is made with an upri ht extending part, 8G, and with a weiar itod ,horizontal extension, 3T. so that when those parte are in the upper part. of the chain travel the lovers wil stand upright. as shown in Fig. 7. la those positions they are adapted to engage with spurs. 40, one of which projects downward from each car, so that as one of. the car pushers approaches beneath the car and the spar i0 is engaged hy an inclined forward face on one of the levers the latter will -swing downward and permit the spur to he engaged hetween the two adjacent faces. 36. The two plates 30 and the two platos 31 of the. two drivin links also form journals` for transverse. s afts. 42, on which are tiangcd wheels, 43, running on a pair of horizontal rails. 44, to guido the upper length of chain between the two sprockets and takethe vertical con ponont of the thrust of the driving links against the cars so that. the links will not bccomc disengaged: and iu addition the chain is provided at. intervals with rollers, 48, which likewise run` on the rails 1li and keep the chain vfrom dragging.

i The driving 'Thann :25 is driven through machinery located adjacent to the fixed ap proachltrack, which is best shown in Fig. 3. This` machinery includes a motor or other source if-power, 55. which is geared to a shaft 56 through a pinion and gear. 57 and 58,A respectively,thc shaft t. having. fixed to it aA heavy fiy wheel. 60. to aeisist the motor in taking up the load when the machinery is Started as will be described hereinafter. The shaft 56 in turn is geared through reduction gearing, (i1, to a shaft (i3. and on this shaft. is a clutch, G5, hy means ot' which it may be engaged with a shaft tG carrying the chain sprocketl 27; the cinte- (i5 being of well known form and its` pa. ieular dev sign or construction not v constituting any art of the present invention. 'The clutch is eneaged and disengaged through a sot of clutch dogs 70 and a sliding cone 7l, with a Collar and a lon lever 7.5 to impart move.- ment to the clutc collar. The end of the lever 75 is connected through a hell-crank lever 76 anda rod 7T to a hand and foot lever 78. and it will he seen that a movement. of the upper end ot' the lever 78 to the left. as it, is illustrated in Figs. 1 and 3, will ast. to wedge the clutch conc hetween the endsl of the clutch dogs and engage the clutch: while a reverse movement of the lover will not-to disengage the clutch.

In addition there is provided a hrake drum 80, with a hrakc hand 8], on 'the shaft.` 66, the brake band beiner contracted on the: drum hy the downward movement of an;` arm 85 carrying a weight. 8'6; and the brake is released through a cahlo 88 passing over pulleys and connected to the clutch lever 75, so that a movement of this lever t0 engage the clutch will automatically release the brake and a reverse movement of the lever to throw out the clutch will permit thc hrako to be ap lied through the weighted arm.y B5.

Tt wil thus be seen that when the hand lover T8 is operated to set the machinery into motion, the driving chain Q5 will ho started to engage with the cars and draw them toward the tipple and their forward movement will continue until they arc automatically stopped by other parts of the ap aratns which are designed and arranged as allows:

'lhe movement it the clutch lever 75 to engage the clutch also acts through a rod 95 and a hell-crank lever 96 to pull on a oahlc 97 which is connected to a. crank arm 98 on a trans-volse shaft 99 below thc track hed and under the toi part of the, chain 25; the shaft 99 having lixed to it an upwardly projecting crank arm 100. When the clutch is engaged to start the machinery as' above. described the pull imparted through the rod 95 and the cable 97 to the arm 98 on the shaft 99) sets the crank l0() in an upright position, as shown in Fig. 1. and the cars are then impellod forward until the upper end of the crank arm 100 is engaged by a lug 105 on the chain; which impartsv a reverso movement to the shaft 99. This is transmitted hack through the eahle 97 and. the rod 95 and pulls the clutch out of engagement and applies the. brake 8l to stop the machinery. The driving chain :'25 is prf vided with'onc or more lugs, 105i spaced according to the uumher of cars which are. to he accommodated in the tipple 'r'or each dumping operation so that the machinery will heV stopped at the required intervals; and accordingly in the design here illusv trated. which is adapted to handle two cars in the tipple for each operation, the, chain is shown with four car-pusher links, of which latter two alternate ones are cach provided with a stopping lng. 105, formed by making the side plates 3l of one link considerably wider than the others and shaping these plates to rovide triangular projoetions hclow tho pitch line of the chainL y In addition to the anton-tatie stoppingr and braking of the driving machinery as above described, means aro provided for automatically spragging the cars on their rails to hold the train Stationary toi.` the dumping operation, these means comprising parts as follows:

At a point in the track bed below the fixed piece ot' approach track leading to the tipple there is arranged a heavy curved horn or stop 120 which is hinged at one end and adapted for upward or downward movement ahout its pivotv point to engage. a wheel of one of the ears. or to release the wheel from engagement. The horn is raised and 1owered through a pair of toggle links 125, which Elatter are operated through a crank arm 126 on a toggle shaft 127. Tolthe end of the crank arm 120 is fastened a long cable 128 which is led over a sheave and connected at its other end through a bell-crank lever 130 and a rod 131 with the clutch lever 75, so that the movement of the clutch lever to engage the clutch, as above described, will act through the bell-crank lever 130 to impart a pull on the cable 128 and to the toggle arm 126. This bends the toggle joint and draws the horn' 120 downward, thus releasing the cars and ermittin them to travel forward. When t e toggle ]oint is thus bent to withdraw the horn 1t is latched in its bent position by a hooked lever 140 which engages a pin 141 in the toggle joint, so that the horn is held down, against the action of a counter weight 142 which tends to rai the horn. The latch 140 is connte through a bell-crank lever 145 and a rod or cable 146 with a crank arm 148 on the shaft 99, so that the action of these parts is as follows:

When the clutch is engaged to set the driving machineryv into motion the pull on the cable 128 bendsI the toggle joint to withdraw the car stop 120, which latter is then latched in its released position by the latch lever 140. When the cars have run the required distance and one of the lugs 105 engages the end of the crank arm 100 to rotate the shaft 99 and withdraw the clutch and apply the brakes as above described, the same movement ofthe shaft 99 acts through the rod 146 and raises the latch lever '140, thus permitting the counter weight 142 to set the horn and hold the car.

In the track bed of the fixed piece of trackl beyond the tip le there is arranged a car stopping and olding mechanism in all respects similar to the horn 120 and its related parts, the second car stopping mechanism comprisin larly-actnated t rough a counter weight 161 to raise it into its operative position, and released through a palr of to? le links 1,64; with a latch lever 165 to ho d; it in its released position. The toggle linksare bent to withdraw the horn throu h a crank` arm 170 and a. long cable 171, which latter isled over a sheave and connected to a third arm, 172, of the bell-crank lever 130' so that the same movement of the latter which releases the horn 120 likewise releases4 the horn 160. Similarly the latzh lever 165 is withdrawn, to release the togglelateh and permit the horn to be set,"by a long cable 180 which is connected with a crank arm 18.1 on the shaft i 09 carrying the arm 98; so that the came movement of this shaft which withdraws the latch 140 will likewise withdraw the latch 165 and permit the two horns to be set itogether, and the train will be spradgged on the umping each side of the tipple during such double operation. The purpose o a horn or stop 160 siml- V spragging is to hold the train with the couplings slack and the bumpers apart, thus permiltin the car or cars in the tipple to overturn In the operation of the complete mecha mism the motor 55 is first started and the driving machinery set into motion through the lever 78 and the clutch arm 75, lo start the driving chain and move the cars for ward; this same operation of the parts setting the lever 100 into an upright position and in the ,path of movement of the two lu l 105. The train of'cars will thm he driven forward until one of the lugs 105 engages the upper end of the crankarm 100, w` ch will impart a ull back through the cable 97 and the roc 95 to withdraw the clutch and apply the brake; and the same movement, of the parts will withdraw the two latch levers 140 and 165 and permit the two horns or stops to come up and hold the train stationary while the tipple is operated. As soon as the cars in the tipple have been restored to their upright sition the lever 78 may be operated to re ease the two car stops and again set the. machinery into motion and continue the forward movmnent. of tl'e train.
